Matthew 16:1-4 And the Pharisees and Sadducees having approached testing Him, asked Him to show them a sign out of heaven.

BLB⁽ⁱ⁾ ¹ And the Pharisees and Sadducees having approached testing Him, asked Him to show them a sign out of heaven. ² And answering He said to them, “Evening having come, you say, ‘Fair weather, for the sky is red,’ ³ and in the morning, ‘Today a storm, for the sky is red, being overcast.’ Indeed you know how to discern the appearance of the sky, but the signs of the times you are not able! ⁴ An evil and adulterous generation seeks a sign, but no sign will be given to it except the sign of Jonah.” And having left them, He went away.
